Description

Stamping die with hollow cylinder

Technical Field

The utility model relates to the field of stamping dies, in particular to a stamping die with a hollow oil cylinder.

Background

With the development of economy, the automobile is widely popularized, the application of sheet metal parts in the automobile field is wide, the requirements are higher and higher, for some automobile sheet metal parts with wall thickness and high requirement on flatness, the existing conventional stamping die is provided with a spring or a pneumatic top of a punch press, the upper jacking force is insufficient, and the requirement on high flatness cannot be met, so that the conventional stamping die is usually required to be produced by a special machine, the special machine is only used for stamping one sheet metal part and cannot be used for stamping other sheet metal parts, the utilization rate is low, the production cost is high, in the technical field of dies, a batch of products of customers are finished, when the next batch of different products are produced, the die is reworked on the original die to be used for the next batch of products, and the special machine is only used for stamping one sheet metal part, so that the production cost is high.

Disclosure of Invention

The utility model aims to solve the technical problem of providing the stamping die with the hollow oil cylinder, which has the advantages of simple structure, convenient operation, capability of being used for producing sheet metal parts with wall thickness and high required flatness, and reduction of production cost.

The utility model is realized in the following way: the stamping die with the hollow oil cylinder comprises an upper die and a lower die, wherein the upper die sequentially comprises an upper die seat, an upper base plate and an upper die plate from top to bottom, a driving device is arranged at the top of the upper die seat, and a cavity is formed in the bottom of the upper die plate; the lower die is arranged right below the upper die and sequentially comprises a lower die holder, a lower base plate, a lower clamping plate and a pressing plate from bottom to top, a hollow oil cylinder is sleeved in the lower base plate, the upper end of the hollow oil cylinder penetrates through the lower clamping plate and is propped against the bottom of the pressing plate, a male die is fixed in a middle cavity of the hollow oil cylinder, the bottom of the male die is fixed on the lower die holder, and the top penetrates through the pressing plate and corresponds to a cavity of the upper die plate.

Further, a guide post is arranged between the upper die and the lower die.

The utility model has the advantages that: the hollow cylinder is arranged on the lower die of the die, so that the upper jacking pressure of the hollow cylinder is high and is used for jacking the material pressing plate, the cylinder can provide enough upper jacking force when the upper die moves downwards, a special machine is not required, the wall thickness can be conveniently produced, and parts with high flatness are required.

Drawings

The utility model will be further described with reference to examples of embodiments with reference to the accompanying drawings.

Fig. 1 is a schematic structural view of a stamping die with a hollow cylinder according to the present utility model.

The drawings in the specification: stamping die 100, sheet metal part 200, upper die 1, upper die holder 11, upper backing plate 12, upper die plate 13, cavity 131, lower die 2, lower die holder 21, lower backing plate 22, lower clamping plate 23, pressure plate 24, hollow cylinder 25, male die 26 and guide pillar 3.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1, the stamping die 100 with a hollow cylinder of the present utility model includes an upper die 1 and a lower die 2, wherein the upper die 1 includes an upper die holder 11, an upper pad 12 and an upper die plate 13 sequentially from top to bottom, a driving device (not shown) is disposed at the top of the upper die holder 11, and a cavity 131 is disposed at the bottom of the upper die plate 13; the lower die 2 is arranged under the upper die 1, and sequentially comprises a lower die holder 21, a lower base plate 22, a lower clamping plate 23 and a pressing plate 24 from bottom to top, a hollow oil cylinder 25 is sleeved in the lower base plate 22, the upper end of the hollow oil cylinder 25 penetrates through the lower clamping plate 23 and is propped against the bottom of the pressing plate 24, a male die 26 is fixed in a middle cavity of the hollow oil cylinder 25, the bottom of the male die 26 is fixed on the lower die holder 21, and the top penetrates through the pressing plate 24 and corresponds to a cavity 131 of the upper die plate 13. And a guide post 3 is arranged between the upper die 1 and the lower die 2 and used for guiding when the upper die 1 moves downwards.

Working principle: when the driving device drives the upper die 1 to move upwards, the piston of the hollow cylinder 25 of the lower die 2 moves to push the pressing plate 24 upwards, then the sheet metal part 200 is manually placed on the pressing plate 24, finally the driving device drives the upper die 1 to press down so that the upper die plate 13 is pressed onto the pressing plate 24, the pressing plate 24 is continuously moved downwards to be pressed down by pressure, and meanwhile, the piston of the hollow cylinder 25 is pressed down, because the male die 26 is not moved, the top of the male die 26 penetrates through the pressing plate 24 and correspondingly enters the cavity 131 of the upper die plate 13, the shape of the sheet metal part 200 is die-cast, and the upper die 1 moves upwards to take out the sheet metal part 200, so that the cycle work is completed.

According to the utility model, the hollow oil cylinder is arranged on the lower die of the conventional die, so that the upper jacking pressure of the hollow oil cylinder is high and is used for jacking the material plate to replace the traditional jacking action of the spring, and when the upper die moves downwards, the oil cylinder can provide enough jacking force, so that a special machine is not required, the wall thickness can be conveniently produced, and parts with high flatness are required. The stamping die with the hollow oil cylinder is simple in structure, convenient to operate and capable of reducing production cost.

While specific embodiments of the utility model have been described above, it will be appreciated by those skilled in the art that the specific embodiments described are illustrative only and not intended to limit the scope of the utility model, and that equivalent modifications and variations of the utility model in light of the spirit of the utility model will be covered by the claims of the present utility model.
